Color coated steel ability to adapt in different circumstances

Generally speaking, the service life of coated steel is 50% longer than that of galvanized steel.However, in different areas and different use parts, the use of the same galvanized quantity, the same coating, the same coating thickness of the color coating plate, its service life will be very different.For example, in industrial areas or coastal areas, corrosion speeds up and service life is affected by sulfur dioxide gas or salt in the air.

In the rainy season, the coating is soaked by rain for a long time, or in the temperature difference between day and night is too large and easy to condensation parts, will be corroded faster, and the service life will be reduced.Buildings or factories made of colored coated steel plates often have a longer service life when they are washed by rain, otherwise, they will be affected by the effects of sulfur dioxide gas, salt and dust.Therefore, in the design, if the slope of the roof is greater, it is not easy to accumulate dirt and other dirt, the longer the service life;For those areas or parts that are not often washed by rain, they should be washed regularly with water.
